TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 636,293, dated November 7, 1899.

Application filed March 28,1898- Serial No. 675,367. No model.)

To all whom) it may concern.-

Be it known that I, FREDERICK A. ScHos- SOW, a citizen of the United States, residing at Detroit, county of Wayne, State'of Michigan, have invented a certain new and useful Improvement in Tobacco-Pipes; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to tobacco-pipes, and has for its object a construction insuring the rapid radiation of the heat through the stem for the purpose of securing a cool smoke and at the same time providemeans to obstruct the passage of the nicotine to the mouth of the smoker.

Figure l is a longitudinal sectional view through thepipe. Fig. 2 is a perspective view showing in detail my improved construction.

In the drawings, A is the pipe-bowl.

A is the stem, and A the mouthpiece.

B is a central pin secured to the mouthpiece A and enlarged at b to fit the opening a. in the stem A.

Secured to the end of the central pin B where it enters the bowl A is a plug of ashestos b or other suitable material inclosed by the metallic band I), in which are out grooves or passage-ways b for the passage of smoke.

C is a spiral passage-way for the smoke around the central pin B and may be formed thereon or, as shown in the drawings, consist of a coiled wire, preferably aluminium, wound spirally around the pin. By this construction it will be seen that the smoke is drawn through a long tortuous passage,which brings it-in close proximityto the inner walls of the stem, thus insuring rapid radiation of the heat. l

The asbestos plug b aids materially in retaining the heat within the bowl, thereby assisting the spiral passage in producing what is termed a .cool smoke.

The opening a, in the stem A is comparatively large and of uniform diameter throughout its length, and when the spiral way is re-" of air through the pipe, thereby preventing either from reentering the pipe or the mouthpiece or from entering the spiral Way while the pipe is maintained at an angle ordinarily consistent with smoking. In this construction the spiral way should begin and terminate on or above the line of the passage-ways b and the passage-way b and thus provide for a free draft through the pipe. This will prevent the saliva or nicotine from entering the spiral way. It will also be noticed that the coil of wire around the stem being cool will condense the moisture contained in the smoke and cause the same to collect on the surface of the wire, thus insuring what is known as a dry smoke.

It will be seen that the pipe may be readily cleaned throughout its entire length, the smoke delivered will be comparatively dry, cool, and free from impurities, and nicotine cannot reach the mouth of the smoker, nor can the saliva, which may enter the stem, be drawn into the mouth.

What I claim is'- In a tobacco-pipe the combination of the bowl, a stem provided with an enlarged opening through and into the bowl, a removable pin having a spiral way around it, a reducing-plug at the end of the pin, said plug provided with passage-ways leadingto the spiral way, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
